USE OUR NEW HT-300W-12V-DC AS A REPLACEMENT.

THIS UNIT HAS BEEN DISCONTINUED. USE OUR NEW HTF-300W-12V-DC AS A REPLACEMENT.

Our dimmable LET 303 DC 12Volts/300Watts lightech electronic low voltage halogen lighting transformer can be dimmed by low cost TRIAC dimmers without producing any acoustic noise, which is a common problem for other electronic transformers. The most compatible dimmers for our low voltage transformers are “trailing edge” or “reverse phase” wall dimmers which are commonly called electronic low voltage dimmers.

Reset able electronic short circuit protection. Auto-reset overload protection. Auto-Reset thermal cut-off at 125ºC.
